The Internet of Things (IoT)services and application were increasing during the last years in several life fields causes need to provide a secure identifier for protecting sensing data passing between IoT sensors/devices and embedded-subsystem connected by networks. This paper was proposed an algorithm for helping in IoT communication security can used in different IOT entities used in unofficial industrial machine to machine (M2M) communications, smart energy-grids, home or buildings and other computing devices. This paper proposed a secure system using new proposed 4D chaotic system combined with the modified lightweight Advanced Encryption Standard (AES). The proposed 4-dimension (4D) chaos system Lyapunov was tested and pass for many initial periods and get a super chaos system (4 positive Lyapunov). Generated chaos keys (used JORN) were used in the lightweight AES and the Secure Hash Algorithm version 3 (SHA3-256). The Lightweight AES was design in case to reduce CPU computation cycles and complexity of AES. Results show that computation time for proposed system decreased (has 145% speedup more). The output of modified lightweight AES encryption System has the good statistical tests near to original AES that can avoid many attacks.

The Advanced Encryption Standard (AES) encryption algorithm is a block cipher that uses an encryption key and a several rounds of encryption. A block cipher is an encryption algorithm that works on a single block of data at a time. In the case of standard AES encryption the block is 128 bits, or 16 bytes, in length. The term “rounds” refers to the way in which the encryption algorithm mixes the data re-encrypting it ten to fourteen times depending on the length of the key[1]. The AES algorithm itself is not a computer program or computer source code. It is a mathematical description of a process of obscuring data. A number of people have created source code implementations of AES encryption, including the original authors.In this paper we introduce a development study for the AES with new permutation of portion. Since we add initial permutation to beginning of AES encryption and when decrypt add permutation inverse to its end. These make it more confusion then orginal AES.

Advanced Encryption Standard (AES) is a symmetric-key encryption each ofthese ciphers has a 128-bit block size, with key sizes of 128, 192 and 256 bits. The AES cipher is specified as a number of repetitions of transformation rounds that convert the input plaintext into the final output of ciphertext. Each round consists of several processing steps, including one that depends on the encryption key[1,2]. This research proposes a technique intended to make the Advanced EncryptionStandard (AES) more safe and secure. Through the generation of random key, and permutation key sites in each round, instead of the process of expanding key locations in addition to the proposed permutation the plaintext before entering the encryption and inverse permutation for resulting ciphertext.

Today, computers and mobiles devices become an essential part that people use to perform a major part of their daily activities. Those devices sometimes become meaningless without being connected to the internet. In addition, people exchange tens of their data cross multiple devices that are connected remotely using internet, the thing that make such data are exposed to be captured. Hence, to overcome such concerns, there is a big necessity to continuously develop new methods to mitigate the threat of data capturing by anonymous people. In this research, we present a method to encode human fingerprint using quick response code (QR Code). The method involves extracting the fingerprint minutiae which depicts the most important features of fingerprint, then that features are turned into image of QR Code format. This method ensures transferring a data with good level of safety since the real data are difficult to be guest. To make the process more complicate, we encrypted the fingerprint features by using (AES) encryption method which make the data meaningless event when they captured by anonymous intruders. After method implementation, the values of PSNR and MSE are calculated to evaluate the performance by comparing the original image with the reconstructed one. The results of the method proved that encoding the fingerprint using QR Codes can be successfully performed and utilized with different applications

In this work, we present some deeper insights in the state-of-the-art in block cipher design. This is mainly achieved by assessment of the evaluation process of the AES (Advanced Encryption Standard). We conclude (with may be a little bit surprising result) that the required security level, for a block cipher to be used for the present and foreseeable future, may be underestimated during AES evaluation. In accordance, we propose a new block cipher that we call Nahrainfish, which we believe that it offers the required security level without a big sacrifice in efficiency and other related criteria. Instead of building Nahrainfish totally from scratch, we have made a benefit mainly from some AES finalists to develop the new cipher by an over-engineering approach leading to the required higher security level. Nahrainfish is a classical Feistel network based on a novel combination of both key-dependent S-boxes and data-dependent rotations. It operates on 128-bit blocks and accepts a variable key length up to 1024 bits. The paper also includes some important notes on the security and performance of the cipher.

In this paper, a new secret-key block cipher called 128-bits Blowfish isproposed which is an evolutionary improvement of 64-bits Blowfish designed tomeet the requirements of the Advanced Encryption Standard (AES) to increasesecurity and to improve performance. The proposed algorithm will be used avariable key size up to 192 bytes. It is a Type-3 Feistel network iterated simplefunction 16 times. Specifically, in this proposed algorithm, a combination of fourS-boxes lookups, multiplications as well as fixed and data-dependent rotations willbe used. Mixing round provide different levels of security, efficiency, flexibilityand good avalanche effect. The proposal is word-oriented, in that all the internaloperations are performed on 32-bit words. So it is possible to implement thealgorithm on smart cards efficiently.
